eufy vs Tapo Door Sensors Compared
Power source
You get different battery types for these sensors. The eufy Security Entry Sensor uses one CR123A battery. It claims a two-year life, or 800 days of monitoring. The Tapo T110 Mini uses a CR2032 coin cell. Tapo states it lasts up to two years if triggered less than 30 times daily. The CR2032 is a smaller, more common battery type found in many small electronics. The CR123A is slightly larger but also widely available. Both rely on single batteries, so replacement frequency is low for either. You should check local availability for your preferred battery size before buying.
Physical size
Form factor matters for discreet installation. The eufy sensor measures 2.91 inches long, 1.1 inches wide, and 0.87 inches high. It weighs 2.4 ounces. The Tapo T110 is much smaller. It measures 2.42 inches long, 1.48 inches wide, and only 0.48 inches high. It weighs just 0.92 ounces. The Tapo unit is significantly thinner and lighter. This makes it easier to mount on thin window frames or inside cabinets without being obvious. The eufy unit is bulkier, which might be more noticeable on certain door frames. If space is tight, the smaller Tapo sensor is the better choice.
Hub requirement
Connectivity depends on the hub you already own. The eufy Entry Sensor requires the eufy Security HomeBase to function. It does not connect directly to Wi-Fi. You must have the HomeBase in your system. The Tapo T110 requires the Tapo Hub H100. It also does not connect directly to Wi-Fi, using Sub-1G wireless to talk to the hub instead. Both systems need a central hub to bridge the sensor to your phone. Neither sensor works standalone. You must ensure you have the correct hub for the brand you choose, as they are not cross-compatible.
Alarm volume
Local alarms provide immediate deterrence. The eufy system triggers a 100-decibel siren on the HomeBase when forced entry is detected. You can enable or disable this feature. The Tapo Hub H100 includes a 90-decibel ringer with 19 different tones. You can program the hub to activate the siren as a warning. The eufy sensor offers a slightly louder 100-decibel alert. The Tapo hub offers more variety in sound options. Both levels are loud enough to alert people in the home. The difference is minimal, but eufy has a slight edge in maximum volume output.
Smart automation
Integration with other devices adds value. The Tapo T110 supports Smart Actions. You can program it to turn lights on or off, or disable a Tapo camera when a door opens. This works even if the network is disconnected. The eufy sensor data does not mention specific smart actions or automations beyond basic alerts. It focuses on entry detection and siren activation. Tapo offers more flexible automation possibilities for your other devices. If you want your doors to control lights or cameras, Tapo provides that functionality out of the box.

Users wanting simple installation without extra hubs
The eufy Security Entry Sensor connects directly to a HomeBase, so you do not need a separate hub for basic operation. It uses a CR123A battery that lasts up to 800 days.

Those prioritizing maximum siren volume
If loud alerts are your priority, the eufy Security sensor triggers a 100-decibel siren on the HomeBase. This is louder than the Tapo T110, which uses a 90dB ringer on its hub. The eufy sensor sends smartphone alerts when forced entry is detected. You can toggle the siren protection on or off. It works with optional 24/7 monitoring services.
Shoppers seeking a compact and lightweight sensor
The Tapo T110 Mini is smaller and lighter than the eufy option. It weighs only 0.92 ounces and measures 0.48 inches in length. The eufy sensor weighs 2.4 ounces and is longer. Tapo includes 3M adhesive for easy mounting on nearly any surface. It monitors windows, cabinets, and mailboxes. The design is minimal and fits discreetly on frames.
